I got a 5hp 2500psi pressure washer and now it has no pressure. Im assuming the seals or something is gone in the pump, but are they even repairable or do you just throw it away. I know northern tool sells pumps but are they any better?

Has it frozen? Lot of times they have water in them and they will freeze damaging the pump.

All depends on what you have.

make sure its getting enough pressure from your hose that feeds it. i recently bought a replacement pressure washer to replace the one i had that started doing the same thing as yours only to find out that it had the same problems as the old one (no pressure), were on a well so i swapped out the inline water filter in the house and tada they both worked again.

If it is a name brand, I'd disassemble it and see what is up.

Check the unloader valve if it has one, may be stuck open. Mike

One tip is to change the pump oil now and again. With any luck the pump should last longer and the only issue would be the occasional stuck valve. For that I have been using a spray can pump preservative.
Seems like the engines on the pressure washers out last the pumps by a huge margin and the pumps are not cheap to replace.

I repaired a Kacher for a guy at work. Simple design easy to work on. Parts were pretty cheap to boot. His the pressure was down and pulsated. I don't remember what I replaced but I do remember that it was obvious once I got it torn down. His had a 5hp GC Honda vertical shaft.
Now I have worked on the cheaper pumps that have to exposed sheet metal connecting rods, and all the repairs only seemed to last a short while, plus they are loud and sound cheap. I would not repair one of these again, well maybe I would if thats all I had, haha.

I'm assuming we are talking about the pump unit it's self.
If it's an axial pump replace it. They weren't made to last a very long time. If it's a triplex pump, it may only be a small problem. At the very worst, they are rebuildable for a fraction of the cost of a replacement.

I have one that the pump was crudded up with mineral deposits. I took it apart and cleaned it out, and it works much better. I have no idea what brand it is, I did not need any new parts. Just clean out the residual mineral deposits thanks to the very hard water we have.
